These high pressure jet nozzles are made from abrasion resistant tungsten carbide. Fashioned after the popular Smith series 65 tri-cone bit nozzles. Their compact size makes them ideal for incorporating into various downhole tools, including but not limited to, bits, hole openers, fly-cutter reamers, barrel reamer’s, or any tooling where high pressure, high velocity fluid is required. They are designed to compress fluids as they passed through the nozzle, thus increasing the velocity as fluid passes out the orifice.

High pressure flow across the cutting surface increases ROP (rate of penetration) as well as increasing the life of the cutters. By efficiently removing the cuttings away from the leading edge of the cutter insurers that cuttings are not being re-cut or act as an abrasives which will shorten the life of any cutter.

Nozzles can be ordered in a variety of nozzle sizes ranging from  00|08 | 09 | 10 | 12 | 14 | 16 | 18. For sizes not shown please contact us for availability.

Maximum nozzle size using our standard four-point nozzle retainer is #18/14.287mm. Size 20/15.88mm with a modified retainer design is currently under review.
